I could suggest one that could be modified. It's an american Tichy concrete coaling tower. Normally filled by dumping coal hoppers into an underground bunker the coal is then carried to the 500T coal tower by bucket hoist. This could be modified to carry a four wheel wagon a nd the top of the tower modified to recieve it. Have a look at www.ticytraingroup.com
